Ciao e buona fortuna! David Bowie lyrics (I'm a big fan and like that song a lot, too) are very often intentionally obscure and use turns of phrases that are odd or put together in such a way solely to evoke an image. Such is the case here, I think. Watching people walking around and they seem to be just going through the motions. But this is only an impression of mine. You'd have to ask Mr. Bowie to know for sure.

Ciao,
qui http://marniere.wordpress.com/2013/...ead-with-bowie-thank-you-thank-you-thank-you/ ho trovato "I took it to be two things: one, a play on words, similar to “walking the dog,” and two, a sense of remembering, being nostalgic, longing for people and places and times that have passed. There may be other things going on as well–for all I know, it’s a translation of some clever saying in German". Secondo me potrebbe essere un'espressione del tipo "portare a spasso i fantasmi", nel senso dei ricordi.
